904L Stainless Seamless Tube super austenitic stainless steel is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosion conditions. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking has high resistance, not easy to appear corrosion spots and cracks, pitting corrosion resistance is slightly better than other steel types, with good processability and weldability, can be used in pressure vessels.

904L Stainless  Seamless Tube super austenitic stainless steel is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosion conditions. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking has high resistance, not easy to appear corrosion spots and cracks, pitting corrosion resistance is slightly better than other steel types, with good processability and weldability, can be used in pressure vessels.

The process of the stainless seamless steel tube product determines its limited performance. Generally, the seamless steel pipe has low precision: uneven wall thickness, low brightness inside and outside the pipe, high fixed-length cost, and pitting and black spots on the inside and outside, and its detection; Shaping must be processed offline. Therefore, it embodies its superiority in high-pressure, high-strength, mechanical structural materials.

Stainless steel refers to the air, steam, water and other weak corrosion medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel, also known as stainless acid-resistant steel. Stainless steel wire drawing is the texture of stainless steel surface like silk, this is just a kind of processing technology of stainless steel.

The surface is matte, carefully look at the above a trace of texture, but can not touch out. It is more wear-resistant than general bright stainless steel and looks more advanced

Product Description

Stainless steel seamless pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. 

Stainless steel seamless pipe is a kind of hollow section, no joints around the strip of steel. The thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, its processing costs will rise substantially.
